The load should now be raised to the correct height for that particular stack. Before doing this the operator should look upwards on high stacks in case of overhead obstructions. A glance to either side is usually a good idea too in case pedestrians are around. Operators should not permit anyone to walk near or underneath a raised load.
Note that it is not necessary to go too high as this makes subsequent lining up of the stack more difficult. As a guide, leave about 10 to 15 cm clearance, (4 to 6 ins).
